Abstract

The development of emotions in the offspring of any species, especially humans, is one of the most important and complex processes necessary to ensure their survival. Although other nonverbal expressions of emotion such as body movements provide valuable clues, facial expressions in human infants are arguably the most crucial component in tracking emotional responses. Tracing the developmental path of facial expressions is thus the aim of this longitudinal research study which explores mother-child interactions from infancy to pre-school in Indian culture via video-taped datasets recorded as part of multiple projects spanning Indian universities (IITD, JNU, DU), Osnabruck University and MPI-Netherlands.

Abstract

The present paper assesses discourse-pragmatic factors as a potential explanation for the subject-object assymetry in early child language. It identifies a set of factors which characterize typical situations of informativeness (Greenfield & Smith, 1976), and uses these factors to identify informative arguments in data from four children aged 2;0 through 3;6 learning Inuktitut as a first language. In addition, it assesses the extent of the links between features of informativeness on one hand and lexical vs. null and subject vs. object arguments on the other. Results suggest that a pragmatics account of the subject-object asymmetry can be upheld to a greater extent than previous research indicates, and that several of the factors characterizing informativeness are good indicators of those arguments which tend to be omitted in early child language.

Abstract

This paper examines some of the claims of the Unaccusativity hypothesis.It shows that the supposedly unaccusative ‘die’ verb in Ewe (Kwa), kú can appear as both a one-place and a two-place predicate and has three senses which do not correlate with the number of surface arguments of the verb. For instance, the same sense is involved in both a one-place construction (e.g. she died) and a two-place cognate object construction (she died a wicked death). By contrast, different senses are expressed by formally identical two-place constructions, e.g. ‘the garment die dirt’ (= the garment is dead dirty; intensity) vs., ‘he died ear (to the matter)’ (=he does not want to hear; negative desiderative). The paper explores the learnability problems posed by the non-predictability of the different senses of Ewe ‘die’ from its syntactic frame and suggests that since the meanings are indirectly related to the properties of the event participants, such as animacy, a learner must pay close attention to the properties of the verb’s participants. The paper concludes by demonstrating that the meaning shifts observed in Ewe are also attested in other typologically and genetically unrelated languages such as Japanese, Arrernte (Australian), Oluta (Mixean), Dutch and English.

Abstract

This paper explores the role of various types of location control in descriptions of placement events in Hungarian. It will be shown that general verb choices cannot be explained in terms of spatial relations (such as containment and support) or spatial relational changes (such as joining and separation). On the contrary, all main verb distinctions within the placement domain can be described in terms of agentive control settings between the Figure and agentive entities (e.g., the Agent, other persons). In Hungarian, only events with continuous agentive control along the motion trajectory are described as either ‘putting’ or ‘taking’, and only events where the Figure is furthermore controlled by a non-agentive entity at the Goal are described as ‘putting’.

Abstract

The RELISH project promotes language-oriented research by addressing a two-pronged problem: (1) the lack of harmonization between digital standards for lexical information in Europe and America, and (2) the lack of interoperability among existing lexicons of endangered languages, in particular those created with the Shoebox/Toolbox lexicon building software. The cooperation partners in the RELISH project are the University of Frankfurt (FRA), the Max Planck Institute for Psycholinguistics (MPI Nijmegen), and Eastern Michigan University, the host of the Linguist List (ILIT). The project aims at harmonizing key European and American digital standards whose divergence has hitherto impeded international collaboration on language technology for resource creation and analysis, as well as web services for archive access. Focusing on several lexicons of endangered languages, the project will establish a unified way of referencing lexicon structure and linguistic concepts, and develop a procedure for migrating these heterogeneous lexicons to a standards-compliant format. Once developed, the procedure will be generalizable to the large store of lexical resources involved in the LEGO and DoBeS projects.

Abstract

This chapter provides a partial overview of some currently debated issues in the cognitive science of language. We distinguish two families of problems, which we refer to as ‘language and cognition’ and ‘linguistics and cognition’. Under the first heading we present and discuss the hypothesis that language, in particular the semantics of tense and aspect, is grounded in the planning system. We emphasize the role of non-monotonic inference during language comprehension. We look at the converse issue of the role of linguistic interpretation in reasoning tasks. Under the second heading we investigate the two foremost assumptions of current linguistic methodology, namely intuitions as the only adequate empirical basis of theories of meaning and grammar and the competence-performance distinction, arguing that these are among the heaviest burdens for a truly comprehensive approach to language. Marr’s three-level scheme is proposed as an alternative methodological framework, which we apply in a review of two ERP studies on semantic processing, to the ‘binding problem’ for language, and in a conclusive set of remarks on relating theories in the cognitive science of language.

Abstract

In conversation, listeners frequently encounter speakers with foreign accents. Previous research on foreign-accented speech has primarily examined the short-term effects of exposure and the relative ease that listeners have with adapting to an accent. The present study examines the stability of this adaptation, with seven full days between testing sessions. On both days, subjects performed a cross-modal priming task in which they heard several minutes of an unfamiliar accent of their native language: a form of Hebrewaccented Dutch in which long /i:/ was shortened to /I/. During this task on Day 1, recognition of accented forms was not facilitated, compared to that of canonical forms. A week later, when tested on new words, facilitatory priming occurred, comparable to that seen for canonically produced items tested in both sessions. These results suggest that accented forms can be learned from brief exposure and the stable effects of this can be seen a week later.

Abstract

Analysis of the functions of nominal apposition in a number of Latin authors representing different periods, genres, and
linguistic registers shows (1) that nominal apposition in Latin had a wide variety of functions; (2) that genre had some
effect on functional use; (3) that change did not affect semantic fields as such; and (4) that with time the occurrence of
apposition increasingly came to depend on the semantic field and within the semantic field on the individual lexical items.
The ‘per-word’ treatment –also attested for the structural development of nominal apposition– underscores the specific
characteristics of nominal apposition as a phenomenon at the cross-roads of syntax and derivational morphology

Abstract

The study of first language acquisition still strongly relies on behavioural methods to measure underlying linguistic abilities. In the present paper, we closely examine and model one such method, the headturn preference procedure (HPP), which is widely used to measure infant speech segmentation and word recognition abilities Our model takes real speech as input, and only uses basic sensory processing and cognitive capabilities to simulate observable behaviour.We show that the familiarity effect found in many HPP experiments can be simulated without using the phonetic and phonological skills necessary for segmenting test sentences into words. The explicit modelling of the process that converts the result of the cognitive processing of the test sentences into observable behaviour uncovered two issues that can lead to null-results in HPP studies. Our simulations show that caution is needed in making inferences about underlying language skills from behaviour in HPP experiments. The simulations also generated questions that must be addressed in future HPP studies.

Abstract

In the present paper we investigate the effect of categorising raw behavioural data or computational model responses. In addition, the effect of averaging over stimuli from potentially different populations is assessed. To this end, we replicate studies on word learning and generalisation abilities using the ACORNS models. Our results show that discrete categories may obscure interesting phenomena in the continuous responses. For example, the finding that learning in the model saturates very early at a uniform high recognition accuracy only holds for categorical representations. Additionally, a large difference in the accuracy for individual words is obscured by averaging over all stimuli. Because different words behaved differently for different speakers, we could not identify a phonetic basis for the differences. Implications and new predictions for infant behaviour are discussed.

Abstract

In this chapter, the multilingual systems of bilingual speakers of Sursilvan Romansh and German are analyzed. The Romansh and the German systems show important differences in the domain of placement. Romansh has a fairly general verb metter ‘to put’ whereas German uses different verbs (e.g., setzen ‘to set’, legen ‘to lay’, stellen ‘to stand’). Whereas there are almost no traces of German in the Romansh data elicited from the German-Romansh bilinguals, it appears that their production of German yields uses of the verbs which differ from the typical German system. Although the forms of the German verbs have been acquired by the bilingual speakers, their distribution in the data arguably reflects traces of the Romansh category of metter ‘to put’.

Abstract

In Yukatek Maya, event types are lexicalized in verb roots and stems that fall into a number of different form classes on the basis of (a) patterns of aspect-mood marking and (b) priviledges of undergoing valence-changing operations. Of particular interest are the intransitive classes in the light of Perlmutter’s (1978) Unaccusativity hypothesis. In the spirit of Levin & Rappaport Hovav (1995) [L&RH], Van Valin (1990), Zaenen (1993), and others, this paper investigates whether (and to what extent) the association between formal predicate classes and event types is determined by argument structure features such as ‘agentivity’ and ‘control’ or features of lexical aspect such as ‘telicity’ and ‘durativity’. It is shown that mismatches between agentivity/control and telicity/durativity are even more extensive in Yukatek than they are in English (Abusch 1985; L&RH, Van Valin & LaPolla 1997), providing new evidence against Dowty’s (1979) reconstruction of Vendler’s (1967) ‘time schemata of verbs’ in terms of argument structure configurations. Moreover, contrary to what has been claimed in earlier studies of Yukatek (Krämer & Wunderlich 1999, Lucy 1994), neither agentivity/control nor telicity/durativity turn out to be good predictors of verb class membership. Instead, the patterns of aspect-mood marking prove to be sensitive only to the presence or absense of state change, in a way that supports the unified analysis of all verbs of gradual change proposed by Kennedy & Levin (2001). The presence or absence of ‘internal causation’ (L&RH) may motivate the semantic interpretation of transitivization operations. An explicit semantics for the valence-changing operations is proposed, based on Parsons’s (1990) Neo-Davidsonian approach.

Abstract

Fictive Motion is the metaphoric use of path relators in the expression of spatial relations or configurations that are static, or at any rate do not in any obvious way involve physical entities moving in real space. The goal is to study the expression of such relations or configurations in the target language, with an eye particularly on whether these expressions exclusively/preferably/possibly involve motion verbs and/or path relators, i.e., Fictive Motion. Section 2 gives Talmy’s (2000: ch. 2) phenomenology of Fictive Motion construals. The researcher’s task is to “distill” the intended spatial relations/configurations from Talmy’s description of the particular Fictive Motion metaphors and elicit as many different examples of the relations/configurations as (s)he deems necessary to obtain a basic sense of whether and how much Fictive Motion the target language offers or prescribes for the encoding of the particular type of relation/configuration. As a first stab, the researcher may try to elicit natural translations of culturally appropriate adaptations of the examples Talmy provides with each type of Fictive Motion metaphor.

Abstract

Landscape terms reflect the relationship between geographic reality and human cognition. Are ‘mountains’, ‘rivers, ‘lakes’ and the like universally recognised in languages as naturally salient objects to be named? The landscape subproject is concerned with the interrelation between language, cognition and geography. Specifically, it investigates issues relating to how landforms are categorised cross-linguistically as well as the characteristics of place naming.

Abstract

How do different languages and cultures conceptualise time? This question is part of a broader set of questions about how humans come to represent and reason about abstract entities – things we cannot see or touch. For example, how do we come to represent and reason about abstract domains like justice, ideas, kinship, morality, or politics? There are two aspects of this project: (1) Time arrangement tasks to assess the way people arrange time either as temporal progressions expressed in picture cards or done using small tokens or points in space. (2) A time & space language inventory to discover and document the linguistic coding of time and its relation to space, as well as the cultural knowledge structures related to time.

Abstract

Space and time appear to be related asymmetrically in the child’s mind: temporal representations depend on spatial representations more than vice versa, as predicted by space-time metaphors in language. In a study supporting this conclusion, spatial information interfered with children’s temporal judgments more than vice versa (Casasanto, Fotakopoulou, & Boroditsky, 2010, Cognitive Science). In this earlier study, however, spatial information was available to participants for more time than temporal information was (as is often the case when people observe natural events), suggesting a skeptical explanation for the observed effect. Here we conducted a stronger test of the hypothesized space-time asymmetry, controlling spatial and temporal aspects of the stimuli even more stringently than they are generally ’controlled’ in the natural world. Results replicated Casasanto and colleagues’, validating their finding of a robust representational asymmetry between space and time, and extending it to children (4-10 y.o.) who speak Dutch and Brazilian Portuguese.

Abstract

This chapter outlines two influential "bootstrapping" proposals that draw on presumed universals of argument structure to account for young children's acquisition of grammar (semantic bootstrapping) and verb meaning (syntactic bootstrapping), discusses controversial issues raised by these proposals, and summarizes the new insights contributed to the debate by each of the chapters in this volume.

Abstract

This chapter is about the initial flowering of conditionals, if-(then) constructions, in children's spontaneous speech. It is motivated by two major theoretical interests. The first and most immediate is to understand the acquisition process itself. Conditionals are conceptually, and in many languages morphosyntactically, complex. What aspects of cognitive and grammatical development are implicated in their acquisition? Does learning take place in the context of particular interactions with other speakers? Where do conditionals fit in with the acquisition of other complex sentences? What are the semantic, syntactic and pragmatic properties of the first conditionals? Underlying this first interest is a second, more strictly linguistic one. Research of recent years has found increasing evidence that natural languages are constrained in certain ways. The source of these constraints is not yet clearly understood, but it is widely assumed that some of them derive ultimately from properties of children's capacity for language acquisition.

Abstract

Attempts to explain children's grammatical development often assume a close initial match between units of meaning and units of form; for example, agents are said to map to sentence-subjects and actions to verbs. The meanings themselves, according to this view, are not influenced by language, but reflect children's universal non-linguistic way of understanding the world. This paper argues that, contrary to this position, meaning as it is expressed in children's early sentences is, from the beginning, organized on the basis of experience with the grammar and lexicon of a particular language. As a case in point, children learning English and Korean are shown to express meanings having to do with directed motion according to language-specific principles of semantic and grammatical structuring from the earliest stages of word combination.

Abstract

Kids’ Cut & Break is a task inspired by the original Cut & Break task (see MPI L&C Group Field Manual 2001), but designed for use with children as well as adults. There are fewer videoclips to be described (34 as opposed to 61), and they are “friendlier” and more interesting: the actors wear colorful clothes, smile, and act cheerfully. The first 2 items are warm-ups and 4 more items are fillers (interspersed with test items), so only 28 of the items are actually “test items”. In the original Cut & Break, each clip is in a separate file. In Kids’ Cut & Break, all 34 clips are edited into a single file, which plays the clips successively with 5 seconds of black screen between each clip.

Abstract

How similar are the event concepts encoded by different languages? So far, few event domains have been investigated in any detail. The PUT project extends the systematic cross-linguistic exploration of event categorisation to a new domain, that of placement events (putting things in places and removing them from places). The goal of this task is to explore cross-linguistic universality and variability in the semantic categorisation of placement events (e.g., ‘putting a cup on the table’).

Abstract

The cognitive processes involved in object recognition remain a mystery to the cognitive
sciences. We know that the visual system recognizes objects via multiple features, including
shape, color, texture, and motion characteristics. However, the way these features are
combined to recognize objects is still an open question. The purpose of this contribution is to
review the research about the specific role of color information in object recognition. Given
that the human brain incorporates specialized mechanisms to handle color perception in the
visual environment, it is a fair question to ask what functional role color might play in
everyday vision.

Abstract

Prior work has shown that listeners efficiently exploit prosodic information both in the discourse referent and in the preceding modifier to identify the referent. This study investigated whether listeners make use of prosodic information prior to the ENTIRE referential expression, i.e. the intonational realization of the adverb 'now', to identify the upcoming referent. The adverb ‘now’ can be used to draw attention to contrasting information in the sentence. (e.g., ‘put the book on the bookshelf. Now put the pen on the bookshelf.’). It has been shown for Dutch that nu ('now') is realized prosodically differently in different information structural contexts though certain realizations occur across information structural contexts. In an eye-tracking experiment we tested two hypotheses regarding the role of the intonation of nu in online reference resolution in Dutch: the “irrelevant intonation” hypothesis, whereby listeners make no use of the intonation of nu, vs. the “linguistic intonation” hypothesis, whereby listeners are sensitive to the conditional probabilities between different intonational realizations of nu and the referent. Our findings show that listeners employ the intonation of nu to identify the upcoming referent. They are mislead by an accented nu but correctly interpret an unaccented nu as referring to a new, unmentioned entity.

Abstract

It has been claimed that Dutch listeners use suprasegmental cues (duration, spectral tilt) more than English listeners in distinguishing English word stress. We tested whether this asymmetry also holds in production, comparing the realization of English word stress by native English speakers and Dutch speakers. Results confirmed that English speakers centralize unstressed vowels more, while Dutch speakers of English make more use of suprasegmental differences.

Abstract

Sentences with contrastive intonation are assumed to presuppose contextual alternatives to the accented elements. Two cross-modal priming experiments tested in Dutch whether such contextual alternatives are automatically available to listeners. Contrastive associates – but not non- contrastive associates - were facilitated only when primes were produced in sentences with contrastive intonation, indicating that contrastive intonation makes unmentioned contextual alternatives immediately available. Possibly, contrastive contours trigger a “presupposition resolution mechanism” by which these alternatives become salient.

Abstract

INTRODUCTION It is nowadays well established that spoken sentence processing is achieved in an incremental manner. As a sentence unfolds over time, listeners rapidly process incoming information to eliminate local ambiguity and make predictions on the most plausible interpretation of the sentence. Previous research has shown that these predictions are based on all kinds of linguistic information, explicitly or implicitly in combination with world knowledge.1 A substantial amount of evidence comes from studies on online referential processing conducted in the visual-world paradigm (Cooper 1974; Eberhard, Spivey-Knowlton, Sedivy, and Tanenhaus 1995; Tanenhaus, Sedivy- Knowlton, Eberhard, and Sedivy 1995; Sedivy, Tanenhaus, Chambers, Carlson 1999).

Abstract

The present study compared the role of metrical stress in comprehension and production of three-year-old children with a familial risk of dyslexia with that of normally developing children to further explore the phonological deficit in dyslexia. A visual fixation task with stress (mis-)matches in bisyllabic words, as well as a non-word repetition task with bisyllabic targets were presented to the control and at-risk children. Results show that the at-risk group was less sensitive to stress mismatches in word recognition than the control group. Correct production of metrical stress patterns did not differ significantly between the groups, but the percentages of phonemes produced correctly were lower for the at-risk than the control group. These findings suggest that processing of metrical stress is not impaired in at-risk children, but that this group cannot exploit metrical stress for speech in word recognition. This study demonstrates the importance of including suprasegmental skills in dyslexia research.

Abstract

Paper presented at The 161th Meeting Acoustical Society of America, Seattle, Washington, 23-27 May 2011. Reduction in casual speech can create ambiguity, e.g., “he was” can sound like “he’s.” Before quotative “like” “so she’s/she was like…”, it was found that there is little accurate acoustic information about the distinction in the signal. This work examines what types of information acoustics of the target itself, speech rate, coarticulation, and syntax/semantics listeners use to recognize such reduced function words. We compare perception studies presenting the targets auditorily with varying amounts of context, presenting the context without the targets, and a visual study presenting context in written form. Given primarily discourse information visual or auditory context only, subjects are strongly biased toward past, reflecting the use of quotative “like” for reporting past speech. However, if the target itself is presented, the direction of bias reverses, indicating that listeners favor acoustic information within the target which is reduced, sounding like the shorter, present form over almost any other source of information. Furthermore, when the target is presented auditorily with surrounding context, the bias shifts slightly toward the direction shown in the orthographic or auditory-no-target experiments. Thus, listeners prioritize acoustic information within the target when present, even if that information is misleading, but they also take discourse information into account.

Abstract

Although the possibility of referring or citing on-line data from publications is seen at least theoretically as an important means to provide immediate testable proof or simple illustration of a line of reasoning, the practice has not been wide-spread yet and no extensive experience has been gained about the possibilities and problems of referring to raw data-sets. This paper makes a case to investigate the possibility and need of persistent data visualization services that facilitate the inspection and evaluation of the cited data.

Abstract

The DAM-LR project aims at virtually integrating various European language resource archives that allow users to navigate and operate in a single unified domain of language resources. This type of integration introduces Grid technology to the humanities disciplines and forms a federation of archives. The complete architecture is designed based on a few well-known components .This is considered the basis for building a research infrastructure for Language Resources as is planned within the CLARIN project. The DAM-LR project was purposefully started with only a small number of participants for flexibility and to avoid complex contract negotiations with respect to legal issues. Now that we have gained insights into the basic technology issues and organizational issues, it is foreseen that the federation will be expanded considerably within the CLARIN project that will also address the associated legal issues.

Abstract

Within the CLARIN e-science infrastructure project it is foreseen to develop a component-based registry for metadata for Language Resources and Language Technology. With this registry it is hoped to overcome the problems of the current available systems with respect to inflexible fixed schema, unsuitable terminology and interoperability problems. The registry will address interoperability needs by refering to a shared vocabulary registered in data category registries as they are suggested by ISO.

Abstract

Introduction Increasingly often research in the humanities is based on data. This change in attitude and research practice is driven to a large extent by the availability of small and cheap yet high-quality recording equipment (video cameras, audio recorders) as well as advances in information technology (faster networks, larger data storage, larger computation power, suitable software). In some institutes such as the Max Planck Institute for Psycholinguistics, already in the 90s a clear trend towards an all-digital domain could be identified, making use of state-of-the-art technology for research purposes. This change of habits was one of the reasons for the Volkswagen Foundation to establish the DoBeS program in 2000 with a clear focus on language documentation based on recordings as primary material.

Abstract

This paper describes the status of the standardization efforts of a Component Metadata approach for describing Language Resources with metadata. Different linguistic and Language & Technology communities as CLARIN, META-SHARE and NaLiDa use this component approach and see its standardization of as a matter for cooperation that has the possibility to create a large interoperable domain of joint metadata. Starting with an overview of the component metadata approach together with the related semantic interoperability tools and services as the ISOcat data category registry and the relation registry we explain the standardization plan and efforts for component metadata within ISO TC37/SC4. Finally, we present information about uptake and plans of the use of component metadata within the three mentioned linguistic and L&T communities.

Abstract

This study investigates the lexical representation of second-language words that contain difficult to distinguish phonemes. Dutch and English listeners' perception of partially onset-overlapping word pairs like DAFFOdil-DEFIcit and minimal pairs like flash-flesh, was assessed with two cross-modal priming experiments, examining two stages of lexical processing: activation of intended and mismatching lexical representations (Exp.1) and competition between those lexical representations (Exp.2). Exp.1 shows that truncated primes like daffo- and defi- activated lexical representations of mismatching words (either deficit or daffodil) more for L2 than L1 listeners. Exp.2 shows that for minimal pairs, matching primes (prime: flash, target: FLASH) facilitated recognition of visual targets for L1 and L2 listeners alike, whereas mismatching primes (flesh, FLASH) inhibited recognition consistently for L1 listeners but only in a minority of cases for L2 listeners; in most cases, for them, primes facilitated recognition of both words equally strongly. Importantly, all listeners experienced a combination of facilitation and inhibition (and all items sometimes caused facilitation and sometimes inhibition). These results suggest that for all participants, some of the minimal pairs were represented with separate, native-like lexical representations, whereas other pairs were stored as homophones. The nature of the L2 lexical representations thus varied strongly even within listeners.

Abstract

This paper presents experimental evidence that cognates can trigger codeswitching. In two picture naming experiments, Dutch-English bilinguals switched between Dutch and English. Crucial words followed either a cognate or a non-cognate. In Experiment 1, response language was indicated by a color cue, and crucial trials always required a switch. Crucial trials had shorter reaction times after a cognate than after a non-cognate. In Experiment 2, response language was not cued and participants switched freely between the languages. Words after cognates were switched more often than words after non-cognates, for switching from L1 to L2 only. Both experiments thus showed that cognates facilitated language switching of the following word. The results extend evidence for triggered codeswitching from natural speech analyses.

Abstract

Listeners’ interactions often take place in auditorily challenging conditions. We examined how noise affects phonological competition during spoken word recognition. In a visual-world experiment, which allows us to examine the timecourse of recognition, English participants listened to target words in quiet and in noise while they saw four pictures on the screen: a target (e.g. candle), an onset overlap competitor (e.g. candy), an offset overlap competitor (e.g. sandal), and a distractor. The results showed that, while all competitors were relatively quickly suppressed in quiet listening conditions, listeners experienced persistent competition in noise from the offset competitor but not from the onset competitor. This suggests that listeners’ phonological competitor activation persists for longer in noise than in quiet and that listeners are able to deactivate some unwanted competition when listening to speech in noise. The well-attested competition pattern in quiet was not replicated. Possible methodological explanations for this result are discussed.

Abstract

How are events framed in narrative? Speakers of English (a 'satellite-framed' language), when 'reading' Mercer Mayer's wordless picture book 'Frog, Where Are You?', find the story self-evident: a boy has a dog and a pet frog; the frog escapes and runs away; the boy and dog look for it across hill and dale, through woods and over a cliff, until they find it and return home with a baby frog child of the original pet frog. In Tzeltal, as spoken in a Mayan community in southern Mexico, the story is somewhat different, because the language structures event descriptions differently. Tzeltal is in part a 'verb-framed' language with a set of Path-encoding motion verbs, so that the bare bones of the Frog story can consist of verbs translating as 'go'/'pass by'/'ascend'/ 'descend'/ 'arrive'/'return'. But Tzeltal also has satellite-framing adverbials, grammaticized from the same set of motion verbs, which encode the direction of motion or the orientation of static arrays. Furthermore, motion is not generally encoded barebones, but vivid pictorial detail is provided by positional verbs which can describe the position of the Figure as an outcome of a motion event; motion and stasis are thereby combined in a single event description. (For example: jipot jawal "he has been thrown (by the deer) lying¬_face_upwards_spread-eagled". This paper compares the use of these three linguistic resources in frog narratives from 14 Tzeltal adults and 21 children, looks at their development in the narratives of children between the ages of 4-12, and considers the results in relation to those from Berman and Slobin's (1996) comparative study of adult and child Frog stories.

Abstract

How do children learn a language whose arguments are freely ellipsed? The Mayan language Tzeltal, spoken in southern Mexico, is such a language. The acquisition pattern for Tzeltal is distinctive, in at least two ways: verbs predominate even in children’s very early production vocabulary, and these verbs are often very specific in meaning. This runs counter to the patterns found in most Indo-European languages, where nouns tend to predominate in early vocabulary and children’s first verbs tend to be ‘light’ or semantically general. Here I explore the idea that noun ellipsis and ‘heavy’ verbs are related: the ‘heavy’ verbs restrict the nominal reference and so allow recovery of the ‘missing’ nouns. Using data drawn from videotaped interaction of four Tzeltal children and their caregivers, I examined transitive clauses in an adult input sample and in child speech, and tested the hypothesis that direct object arguments are less likely to be realized overtly with semantically specific verbs than with general verbs. This hypothesis was confirmed, both for the adult input and for the speech of the children (aged 3;4-3;9). It is therefore possible that argument ellipsis could provide a clue to verb semantics (specific vs. general) for the Tzeltal child.

Abstract

The surge of research activity focussing on children's acquisition of verbs (e.g., Tomasello and Merriman 1996) addresses some fundamental questions: Just how variable across languages, and across individual children, is the process of verb learning? How specific are arguments to particular verbs in early child language? How does the grammatical category 'Verb' develop? The position of Universal Grammar, that a verb category is early, contrasts with that of Tomasello (1992), Pine and Lieven and their colleagues (1996, in press), and many others, that children develop a verb category slowly, gradually building up subcategorizations of verbs around pragmatic, syntactic, and semantic properties of the language they are exposed to. On this latter view, one would expect the language which the child is learning, the cultural milieu and the nature of the interactions in which the child is engaged, to influence the process of acquiring verb argument structures. This paper explores these issues by examining the development of argument representation in the Mayan language Tzeltal, in both its lexical and verbal cross-referencing forms, and analyzing the semantic and pragmatic factors influencing the form argument representation takes. Certain facts about Tzeltal (the ergative/ absolutive marking, the semantic specificity of transitive and positional verbs) are proposed to affect the representation of arguments. The first 500 multimorpheme combinations of 3 children (aged between 1;8 and 2;4) are examined. It is argued that there is no evidence of semantically light 'pathbreaking' verbs (Ninio 1996) leading the way into word combinations. There is early productivity of cross-referencing affixes marking A, S, and O arguments (although there are systematic omissions). The paper assesses the respective contributions of three kinds of factors to these results - structural (regular morphology), semantic (verb specificity) and pragmatic (the nature of Tzeltal conversational interaction).

Abstract

This task has two parts: (i) video-taped elicitation of the range of possibilities for referring to persons and places, and (ii) observations of (first) references to persons and places in video-taped natural interaction. The goal of this task is to establish the repertoires of referential terms (and other practices) used for referring to persons and to places in particular languages and cultures, and provide examples of situated use of these kinds of referential practices in natural conversation. This data will form the basis for cross-language comparison, and for formulating hypotheses about general principles underlying the deployment of such referential terms in natural language usage.

Abstract

Interaction, for all that it has an ethological base, is culturally constituted, and how new social members are enculturated into the interactional practices of the society is of critical interest to our understanding of interaction – how much is learned, how variable is it across cultures – as well as to our understanding of the role of culture in children’s social-cognitive development. The goal of this task is to document the nature of caregiver infant interaction in different cultures, especially during the critical age of 9-15 months when children come to have an understanding of others’ intentions. This is of interest to all students of interaction; it does not require specialist knowledge of children.
